In this section, we study the information paradox in Schwarzschild de-Sitter black hole by splitting our discussion into two subsections for black hole patch and cosmological de-Sitter patch. We shall be using two dimensional CFT formula in s-wave approximation [1]} (observer is very far away from the black hole, i.e, \(b_{1,2}^{\pm } \gg r_{H,C}\) ) to obtain the entanglement entropy of Hawking radiation.
